Integrates Slack messaging with the Icinga2 API.
Slack Icinga2 is a simple PHP application which resides on a webserver, typically a small cloud instance. It accepts slash commands from the Slack messaging application and interracts with the Icinga2 API. The architecture is based on Openstack Cliff in that commands are in human readable form e.g. host downtime create, and uses command plugins. The plugins that are presented to the end user are configurable and may be selectively enabled or disabled as required by your environment. The following commands are currently available:
- help
- host downtime list
- host downtime create
- host downtime remove
- service downtime list
- service downtime create
- service downtime remove
This application in available in rpm and deb flavors. It installs to the following locations:
/etc/slack-icinga2/config.json- Main configuration file/usr/share/slack-icinga2- Main source files/usr/share/slack-icinga2/commands- Command source files/var/log/slack-icinga2/slack-icinga2.log- Audit and debug logging
Your php.ini configuration should set its timezone to be that you wish to output times in.
A typical virtual host configuration will look like the following:
<VirtualHost #:443>
ServerName slack-icinga2.example.com
DocumentRoot /usr/share/slack-icinga2
SSLEngine on
SSLCipherSuite HIGH:!aNull:!MD5
SSLCertificateFile "/etc/ssl/private/slack-icinga2.example.com.crt"
SSLCertificateKeyFile "/etc/ssl/private/slack-icinga2.example.com.key"
</VirtualHost>
